Gene, I'm with you!!
This (see attached blurry pic) is what I look forward to come home to visit every day. I have a 4-step system right now. First, the baggie. Next is one closed case for rooting (fits ~15 cups), then one case with lid slightly cracked (holds 12), then I have the pictured caddy for the sunny window. The baggie is like "kindergarten", where the rootlets are developed. The closed case is like "elementary school" where the roots take time to develop and grow. The cracked-lid case is like "middle school" when 3-4 roots show on the outside of the cup. The iron caddy is like "middle school", I "sleeve" the clear cup with a dark red cup to protect the roots, put them in the caddy, and use it to easily haul them to/from the window day and night.
I will be happy when we arrive at "high school", this is when we go to a 1gal pot, and start to harden off the figs on the back deck (as soon as I kill the squirrels!!!), at which time we graduate and start in the real world.
Right now, I have 11 cupped cuttings in the pictured caddy, 2 MVSB, 1 Negronne, 2 Conadria, 1 Sal (Gene's), 1 Gino's Black, 1 Bethlehem Black, and 2 Latarrula - the large pot is Carolina Dark.
The 5 in front are from the cracked-lid case, from left-to-right Gino's black, Negronne, MVSB, Hardy Chicago, Voiture #217.
